My old classroom was interesting because three side of the classroom were made from glass. I enjoyed sit close to the windows and looking at the view. On the left-hand side of the class, I could easy see the football field. In the mornings, it was full of students exercising. The view from the back of the classroom is also splendid. Close to the school there was a beautiful park with many trees around them. Farther in the distance, I could not enjoy the view of snowy mountains. On the right side of the class was the road. I was always interested to see the drivers in hurry in the morning. The position of the classroom with its view made me felt like I was dreaming. If I was only a child when I studied in that classroom, I will never forget it.
